Generation of Bode and Nyquist Plots for Nonrational Transfer Functions to Prescribed Accuracy
نویسندگان
چکیده
We present interval analysis based procedures for construction of the well-known Bode and Nyquist frequency response plots for nonrational transfer functions. The proposed procedures can be used to construct the plots reliably and to a prescribed accuracy over a user-specified frequency range. The procedures overcome the limitations of the only available method for nonrational transfer functions that is based on arbitrary gridding of the given frequency range. Several important examples drawn from various branches of engineering are used to demonstrate the merits of the proposed procedures.

Notes on Frequency Methods: Gain Margin Phase Margin, Delays, and the Nyquist Map
Using frequency methods, it is possible to determine a great deal of information from the open-loop transfer function. One of the most important facts about a given system which may be determined via frequency methods is the relative stability of the system. There are two principal measures of system stability determined via frequency methods: Gain Margin, and Phase Margin. These two measures m...
متن کاملThe Effect of Erosion on Corrosion Protection Properties of Coal Tar Epoxy Coating
In this work, the effect of erosion on corrosion behavior of coal tar epoxy coating was evaluated using electrochemical impedance spectroscopy (EIS) measurements. The surface morphology of the coating was examined by scanning electron microscope (SEM) after 10, 20, 30, 45 and 60 min of erosion process at an impact angle of 90º. After 10 min of erosion process, the Nyquist plots showed just a si...
متن کاملUncertain Control Systems
Uncertainties in control systems models often have to be taken into account in their analysis and/or design. Negligence of such uncertainties is often unjustifiable and is done only due to lack of methods to treat the uncertainties. The presented work is concerned with analysis and design of interval uncertainty control systems, with regard to clustering of poles inside a simple symmetric bound...
متن کاملBode Plots of First and Second Order Systems
The objective of this lecture is to provide you with some background on the use of transfer functions to perform the so-called frequency response analysis of dynamic systems, also known as analysis based on Bode plots. This method will be later used in the design of control systems.
متن کاملPid Controller Synthesis Free of Analytical Models
In this paper, we show that the complete set of PID controllers that stabilizes a LTI plant and achieves prescribed performance levels, can be computed from knowledge of only the frequency response (Nyquist or Bode plot) of the plant and the number of RHP poles. The result is of practical importance in many situations where transfer function or state space models are not available and a design ...
